IMPROVEMENT IN SHAFT-COUPLING.

The Schedule referred to in these Letters Patent and making part of the same.

To all who-m it may concern Be itI known that I, SETE H. Wnrrnonn, of Decatur, in the county otl Macon and in the State of Illinois, have invented certain new and usefulvImpros-'ements in Coupling for Shafts; and do hereby declare that the following is afulhcletu, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereonniaking a part of this specification.

The nat-ure ot' my invention consists in the construction and arrangement ot' an improved coupling for shafts, as will beherein'after fully set forth.

v1n order to ena-ble others skilled in the art to which my invention appertains to make anduse the saine, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a. side View of two shaftsjoined to- `gether by.my coupling.

Figure 2 is a. similar View ofthe shafts, wit-h a longitudinal vert-ical section of the coupling.

Figure 3 is ari/"end View of the coupling.

A A represent the ends of two shafts coupled towhich is fitted the outer sleeve C, or nut, haring a screw on its inner peripherythe same taperas that on the outside ot' thc inner sleeve.

When thus fitted it; will not;` open or close, but by cuttingr n slot from end to cud through the inner sleeve B, as shown in figs. 1 and 3, it. can beI closed down on the shafts by turning the nut or outer sleeve up onto the screw which holds the shaft firmly and in line. v

.lo prevent the shaft from working endwise, and at the same time help the coupling to hold the shaft, 1 drill'a. hole' through the inuel sleeve B and end of shaft, into which I put a round piu,1), nnd hold them in place bythe outer sleeve or nut, screwed over them.

Having thus fully described my`inveutiou,

What I claim as new, and desire to secure by Letters Patenti, is-

The combination of the shafts A A, pins D D, and lthe inner and outer sleeves B O, all connected together substantially as set; forth.

In testimony that I claim .the foregoing, I have hereunto set my hand this 31st day of' January, 1870.
